FMOD - Unity WebGL No Sound Occasionally

Issue:

When loading the "Go to next scene", sometimes the audio becomes inaudible. This seems to happen if you click within the game window or outside first. I haven't found a consistent way to reproduce this though.

Additional Details:

1. This is using the code from the repository in: https://github.com/fmod/unity-html5-demo/tree/2.02
2. This published version uses "Unity 2020.3.16f1" and "FMOD 2.02.20" (same as the one mentioned in the Github repo).
   1.  I've also used "Unity 2021.3.26f1" with the abovementioned issue.
3. I've tried referring to the page with no luck: FMOD - Platform Specifics (html5webgl)
4. Here is what the FMOD team is able to deploy, their version has no issues: Unity WebGL Player | Unity HTML Demo (fmod.com)
